Rotundo, called "Minnie" by family and friends, works 7 a.m. to 6 p.m. Monday through Saturday at College Landry Shoppe in Buffalo, her son said. Rotundo has been working since she was 15 at a shoe factory in Pennsylvania during the Great Depression, he added.

"She's always enjoyed working, especially talking to new people and meeting new customers," Gary Rotundo said. "She attributes her longevity to her hardworking nature. She says it gives her a purpose, a reason to always wake up in the morning and a reason to always hustle."
